IMPRQVEMENT 1N STRAW- CUTTERS.

. The Schedule referred to in these Letters Patent and'making part of the same,

To whom 'it may concern Be it known that I, GEORGE S. GARTH, of Mill Hall, Clinton county, Pennsylvania, have invented a new and useful Improvement in Straw-Gutters; and

a full clear,

me, reference being had to the accompanying drawing, forming part of this specification.

This invention relates mly up to its position, but in cause too much pressure of the'knife against the fixed bed or cutter. Figure l represents an end elevation of a strawcutter arranged according to my improvement; l

Figure 2 represents a top or plan view of' the same; Figure 3 represents an end elevation of the same, sbowingthe friction-plate and adj usting-screw arranged on the side of the fulcrnm-pin opposite Ato that iu figs. 1 and 2; and

Figure 4 represents a section, of fig. 3. j

Similar let-ters of 1 parts. y

The fulcrum and fulcrum bracket, B, projecting from taken on theline xx eference indicate corresponding permit the knife bed I, for cutting.

The fulcrum-bol tral stud, K, and

t support is provided with a cena segment of an annular projecting rib, L, the one working in a central socket, M, and the other in an annular groove, I in the disk F of the lever E, by which the said lever is supported, so as to take all strain, except that required for holding them together laterally, ofi' the fulernrn-pin, which is made angular 'in cross-section, and has an angular hole provided for it in the part I), to prevent it from turning with the lever.

found best, I pl against the disk Q, for holding t oi the plate C rigidly, whereb from springing away when cu `be forced against it when not small quantities, so as to tur as will be the cas thecutter up to plates I?, or not.

ace a friction-plate, P, fo F, or part G thereof, by a he` cutter close against the When the friction-plate I is placed between the projections O and G, as represented in iig. 2, it may have projections, S, sliding into notches in the part O, to counteract the tendency of the plate to be moved by the oscillating disk or projection G of the lever; and, when the said friction-plate is placed as represented in fig. 4, the part D may be recessed to receive it, the said recess being made in such a manner that the pressure ofthe point of the thumb-screw holds the plate P firmly to its place.

Having thus described my invention,

What I claim as ters Patent, is

The combination, with the the bracket B and parallel projection D, when the lat-py ter is provided with the circular stud K and curved projection L,-and the lever E is provided with the socketed and grooved disk F, and both the disk and projection arranged for clamp A, substantially as specified.
